There's a lot of information in that spreadsheet, and no way to tell what information you're interested in. Before anyone can get close to a capability calculation, we need to know for starters what the process is and what the specifications are.

The data also looks like production quantities vs some production target for different areas/processes. So it's simple count data. each area listed has a different target wchih would imply that the capability of each area is different. The number of results for each unique area is too low to calculate any meaningful capability. One could calculate the overall capability but since each area is different we woudl have to use a simple categorical approach and 'back calculate' a "Cpk" number (Which I can only assuem you mean when you ask for a capability calculation). That said 'capability studies' really were not meant for this high level of a measure of a ny process...

Dear PP,
Do you want the Capability analysis like number of hr and number of parameters inspected (use .U chart ), or Number of hrs and number of record cleared .so 1st focus of the parameters for which you want to do the analysis and then you can decide the which chart is suitable for you(u can take expert comment to use u chart mentioned above)
